Lipoxygenase inhibitory (LOX) and xanthine oxidase (XO), chelating power (CHEL), and oxygen radical absorbance capacity (ORAC) in extracts obtained from the herb of Aerva lanata (L.) Juss. Mean values of three tests with standard deviation (±SD). Explanations: ORAC—calculated as mM Trolox per g of dry extract; LOX, XO, and CHEL—calculated as EC50 (mg per mL). NA—no activity.

Values are presented as mean ± standard deviation (n = 3) and evaluated by one-way ANOVA test (post-test: Tukey). Different superscript letters (a-–f) in the same column denote significant differences at p < 0.05.
